Electroweak Physics and Physics beyond the Standard Model
نویسنده
چکیده
A precise measurement of the top mass is a central goal of the CDF and D0 experiments which, by 2006, collected an integrated luminosity of ∼ 1 fb during the Tevatron run II operations. The top mass enters as an important parameter in the calculation of electroweak (EW) observables. In global fits of the EW observables to Standard Model (SM) parameters, the top mass therefore provides an indirect constraint on the Higgs mass and therefore plays a crucial role in the understanding of the SM Higgs sector. It is hence highly desirable to improve the precision of the top mass measurement in order to reach a precision comparable to that of the other relevant EW parameters, typically of the order 0.1% 1%. Figure 1 which shows a compilation of measurements from both D0 and CDF, witnesses the great progress obtained in the last few years due to the increased statistics, the

متن کاملA quasi-model-independent search for new electroweak scale physics
These proceedings describe Sleuth, a quasi-model-independent search strategy targeting new electroweak scale physics, and its application to 927 pb of CDF II data. Exclusive final states are analyzed for an excess of data beyond the Standard Model prediction at large summed scalar transverse momentum ( P pT ). This analysis of highP pT data represents one of the most encompassing searches so fa...
متن کاملElectroweak Symmetry Breaking and Physics beyond the Standard Model
In order to extend the Standard Model to TeV scale energies one must address two basic questions: (1) What is the complete description of the effective theory of fundamental particles at and below the electroweak scale? and (2) What is the dynamics responsible for electroweak symmetry breaking? The answers to these questions are crucial for addressing the third outstanding question of particle ...
متن کاملPhenomenology Beyond the Standard Model
Written on the ceiling fresco of the beautiful Festsaal of the Österreichischen Akademie der Wissenschaften, are two words: Causarum Investigatio. Just as these words must have inspired Boltzmann and Schrödinger, today we are inspired to investigate the causes and more fundamental structures underlying the Standard Model of particle physics. The Standard Model is in remarkably successful agreem...
متن کاملSolar Neutrino Experiments: New Physics?
Physics beyond the simplest version of the standard electroweak model is required to reconcile the results of the chlorine and the Kamiokande solar neutrino experiments. None of the 1000 solar models in a full Monte Carlo simulation is consistent with the results of the chlorine or the Kamiokande experiments. Even if the solar models are forced arti cially to have a B neutrino ux in agreement w...
متن کاملI : SLAC - PUB - 7654 September 1997 Experimental Studies of Electroweak Physics
Some experimental new Electroweak physics results measured at the LEP/SLD and the TEVATRON are discussed. The excellent accuracy achieved by the experiments still yield no significant evidence for deviation from the Standard Model predictions, or signal to physics beyond the Standard Model. The Higgs particle still has not been discovered and a low bound is given to its mass.
